The problem that the response speed is lowered can be solved.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram illustrating the configuration of an image processing apparatus according to an embodiment of the present invention. The system includes a scanner 400, a data processing apparatus 100, an input / output processing apparatus 200, and an input via a bus 500. This corresponds to a system in which the output device 300 can communicate. The data processing apparatus 100 controls the scanner 400, the input / output processing apparatus 200 and the input / output apparatus 300, that is, controls the entire image processing apparatus of the present invention.

  In FIG. 1, a scanner 400 is controlled by a scanner controller 103, irradiates a document image with a light source (not shown), forms a document reflection image on a solid-state image sensor with a lens, and outputs a raster-like image reading signal from the solid-state image sensor. Is obtained as image information. In a normal image reading operation, the image signal is temporarily stored in the memory 102 and then transferred to the outside through an external interface (not shown) or stored in an internal storage device such as a hard disk or a memory card (not shown). Further, the scanner controller 103 controls the data processing apparatus 100, the scanner 400, the input / output processing apparatus 200 and the input / output apparatus 300 via the internal bus 106 and the bus 500 of the data processing apparatus 100.

  The resolution conversion unit 105 reads an image image held in the memory 102, converts the resolution, and writes it again in another area in the memory 102. In this example, it is used to create coarse image data used for previewing an image read from the scanner 400. Thereafter, the image data in the memory 102 is transferred to the VRAM 203 via the bus 500, and the image read on the LCD display 301 is previewed.

  The screen controller 101 creates screen data to be drawn on the LCD display 301 (for example, screen data representing an operation panel), and then instructs the LCD controller 204 to draw or the screen position input from the touch panel controller 206. Based on the information, processing corresponding to the position information is performed, and new screen data corresponding to the processing result is created.

  Then, the created screen data (for example, screen data representing the operation panel) is temporarily held in the memory 102 in the data processing apparatus 100, and the region where the preview image of the VRAM 203 is present using the DMA transfer via the bus 500. It is transferred to another area and used for drawing on an operation panel, for example.

  The bus controllers 104 and 205 control a bus 500 (for example, a PCI bus) to which the data processing device 100 and the input / output processing device 200 are connected, so that communication with other devices connected to the bus 500 can be performed.

  An input / output processing device 200, a preview controller 201, an internal bus 207, and the like are used to display an operation screen, adjust the enlargement / reduction of the preview image, and move the preview image.

  The input / output device 300 includes a touch panel that functions as an operation panel, and includes an LCD display 301 and a transparent tablet (touch panel 302) stacked thereon. The LCD display 301 is controlled by the LCD 204 controller and stored in the VRAM 203. The drawn image is displayed on the screen.

  The touch panel 302 is controlled by the touch panel controller 206, detects that the user has touched the touch panel 302, and notifies the touch panel controller 206 of the position.

  The image processing unit 202 is controlled by the preview controller 201 and moves the image data read by the scanner 400 by the movement amount designated by the touch panel 302 or from the screen controller 101 based on the magnification designated by the screen controller 101. After enlarging and reducing the input image, processing such as writing a drawing image of the preview image that has been enlarged or reduced into the VRAM 203 is performed.

  Also, the preview controller 201 calculates a resolution suitable for display in the display area indicated by the display position information based on the image display position information and the display magnification information input from the screen controller 101, and the resolution The image data corresponding to is selected from the image data of various resolutions created by the resolution conversion unit 105 and read, and the image data, display position information, and magnification are given to the image processing unit 202. The image processed by the image processing unit 202 is displayed on the LCD display 301.

  FIG. 2 is a schematic diagram for explaining an example of an editing process screen displayed on the LCD display 301 shown in FIG. 1. In FIG. 2, the LCD controller 204 has a plurality of display areas de1 as shown in FIG. ~ De3 can be displayed in a superimposed manner, and further has a function of displaying a mouse cursor or inverting a part of an image.

  In preview display, an operation panel frame and various buttons are displayed as a background area in the display area de1, and a preview image is displayed in the display area de2. The LCD controller 204 manages the background area and the preview image separately, and performs display control so as not to cause a problem of drawing each other area by mistake.

  Next, the processing flow of this system will be described.

  FIG. 3 is a flowchart showing an example of a first data processing procedure in the image processing apparatus according to the present invention, and corresponds to the preview processing procedure by the preview controller 201 shown in FIG. In addition, (1501)-(1507) show each step.

  4 and 5 are schematic diagrams for explaining an example of a thumbnail editing process screen displayed on the LCD display 301 shown in FIG. Also, the screen data (background area and preview image representing the frame of the operation panel, various buttons, etc.) and the preview image shown in FIGS. 4 and 5 are created by the data processing apparatus 100 as already described.

  First, thumbnail (reduced image) data held in the memory 102 shown in FIG. 2 is displayed as a list (1501), and arbitrary image data is selected from the image data 1001 displayed as a preview for the user as shown in FIG. Prompt. Here, the image data 1000-1 to be previewed is selected from the images 1001 according to the user's selection operation instruction (operation of the area representing the image data 1000-1 on the touch panel 302), and the execution button 1002 on the touch panel 302 is selected. Is pressed (1502), and if selected, resolution conversion processing of one of the images is performed (1503). Here, the resolution conversion unit 105 is used to generate 200, 100, 50, and 25 dpi image data in order from the image data held on the memory 102 and hold them in another area in the memory 102. Here, image data with resolutions other than 200, 100, 50, and 25 dpi are generated by the input / output device 200 based on the image data with these resolutions.

  Next, the screen controller 101 draws a portion other than the image display area 1101 in the preview screen shown in FIG. 5 as a background (1504). Next, the initial resolution is calculated so that the entire selected image fits in the image display area 1101, and the display position information of the image on the screen, display resolution information, and the selected image are transmitted to the preview controller 201 (1505). ). The preview controller 201 selects the image data having the resolution closest to the calculated resolution from the image data created in step (1503), reads it from the memory 102 (1506), and instructs the preview controller 201 to preview the image data. The image is displayed in the image display area 1101 (1507), and the process ends.

  Next, processing after the transition to the preview screen shown in FIG. 5 will be described with reference to FIG.

  FIG. 6 is a flowchart showing an example of a second data processing procedure in the image processing apparatus according to the present invention, and corresponds to the preview processing procedure by the preview controller 201 shown in FIG. Note that (1401) to (1408) indicate each step.

  First, in step (1401), when the touch panel controller 206 waits for the input of position information from the touch panel 302 and detects that the position information has been input by the user's operation, it notifies the preview controller 201, and step (1402). ), It is determined whether the position information is a preview area or not, and if it is determined that the position information is a preview area, the processing following step (1403) is performed on the input / output processing device 200 side, and the preview area If it is determined that it is outside, the processing from step (1407) onward is performed on the data processing apparatus 100 side as described later.

  By doing this, even when the user drags the screen during previewing, a situation in which a large amount of positional information and image data is transferred and the bus 500 is occupied can be avoided, and the data transfer processing is reduced. can do.

  In step (1403), the preview controller 201 recalculates the position and enlargement ratio of the image to be previewed based on the position information input from the touch panel 302. Thereafter, in step (1404), the recalculated preview image data is displayed on the LCD display 301 through the LCD controller 204. Next, after waiting for input of position information from the touch panel controller 206 (1405), it is determined whether or not the drag operation is continued on the touch panel (1406). The continuation of the drag operation is determined based on whether or not the state where the touch panel is being pressed continues. If the drag operation is continuing, the process returns to step (1403) to determine the moving location. If the drag operation for recalculating the position is not continued, the process is terminated.

  On the other hand, if it is determined in step (1402) that position information outside the preview area has been input, in step (1407), the input / output processing device 200 transmits the input position information via the bus 500 to the data processing device. Forward to 100.

  In step (1408), the data processing apparatus 100 acquires information such as buttons arranged at the position on the screen based on the position information, performs the corresponding process, and ends the process. To do.

  FIG. 7 is a flowchart showing an example of a third data processing procedure in the image processing apparatus according to the present invention, and corresponds to the preview processing procedure by the preview controller 201 shown in FIG. In addition, (1601)-(1606) show each step. In this example, in the screen display example shown in FIG. 5, when the enlarge button 1102, the reduce button 1103, or the whole button 1104 is pressed, the screen controller 101 passes through the input / output processing device 200 from the touch panel controller 206. The screen controller 101 changes the button color so that the user knows that the button has been pressed and transmits it to the input / output processing device 200 in accordance with the flow of FIG. After redrawing (1601), after recalculating the resolution of the image displayed on the LCD display 301 (1602), a preview image corresponding to the new resolution is read from the memory 102 (1603), and the display position of the image is set. Recalculate (1604), perform preview area drawing processing (1605), and convert the preview image to LC After displaying on the display 301, button re-drawing was carried out (1606), back to the original display of the button, the process is terminated.

  FIG. 8 is a diagram showing an example of a preview display screen displayed on the LCD display 301 shown in FIG. 1, for example, after the enlargement button 1102 has been pressed several times in the state of the display screen shown in FIG. Corresponds to the screen display. Hereinafter, processing when the rotation button 1105 is pressed will be described with reference to a flowchart shown in FIG.

  FIG. 9 is a flowchart showing an example of a fourth data processing procedure in the image processing apparatus according to the present invention, and corresponds to the preview processing procedure by the preview controller 201 shown in FIG. In addition, (1701)-(1707) show each step.

  Similarly, when the screen controller 101 is notified that the rotation button 1105 has been pressed, the screen controller 101 changes the color of the button to draw (1701), and the data processing apparatus 100 (not shown) displays the image held in the memory. The image processing unit rotates (1702), converts the resolution, and transmits it to the input / output processing device 200 (1703). The input / output processing device 200 reads a preview image corresponding to the current enlargement ratio of the preview ( 1704), the display position of the new image is calculated (1705), the preview image is displayed (1706), and then notified to the screen controller 101. The screen controller 101 creates and inputs the image with the button display restored. The data is transmitted to the output processing apparatus 200, displayed (1707), and the process ends.

  As described above, when the operation button is pressed, the display position information, the button image, and the preview image are transmitted to the input / output processing device 200 via the bus 500. If such control is executed even during the drag operation of the preview image, information is frequently exchanged between the data processing device 100, the input / output processing device 200, and the data on the bus 500, and the bus 500 is substantially transmitted. Will be occupied. For this reason, the efficiency of other processing is significantly reduced. However, as described with reference to FIG. 6, in this embodiment, the preview image is not transmitted to and received from the data processing apparatus 100 during the preview image drag operation. It does not cause a decrease in the processing efficiency of other processes.

  On the other hand, when the screen controller 101 is notified that the arrow button 1106 or the arrow button 1107 is pressed, if a plurality of images are selected in step (1502), another image is displayed according to FIG. To do.

  FIG. 10 is a flowchart showing an example of a fifth data processing procedure in the image processing apparatus according to the present invention, and corresponds to the preview processing procedure by the preview controller 201 shown in FIG. Note that (1801) to (1805) indicate each step.

  First, the screen controller 101 changes the button color to draw (1801), calculates the initial resolution, and transmits it to the input / output processing device 200 (1802). The input / output processing device 200 displays a preview image corresponding to the resolution. After reading (1803) and displaying a preview image (1804), the screen controller 101 creates an image with the button display restored, transmits it to the input / output processing device 200, displays it (1805), The process ends.

  On the other hand, when the quit button 1108 shown in FIG. 5 is pressed, the screen 1000 shown in FIG. 4 is drawn, and the process ends.

  Here, an example in which the input / output processing device 200 performs processing without performing processing in the data processing device 100 regarding the drag operation of the preview image has been described, but is not limited thereto.

  As for the above-described image processing such as enlargement / reduction processing and rotation processing, the image processing may be performed by the input / output processing device 200 without performing the image processing in the data processing device 100 as shown in FIG. That is, when a change is made to the displayed image, the image data has already been transferred, and the image processing is performed in the input / output processing device 200 without performing the image processing in the data processing device 100, thereby The usage efficiency of 500 can be further increased.

  According to the above embodiment, in the image processing apparatus in which the main CPU (first data processing means) that performs normal processing and the I / O CPU (second data processing means) that performs only input / output processing are connected by a bus. Of the processes related to the screen display, the process related to the preview operation is separated and processed on the I / O CPU side, and the position information input to the touch panel during the preview operation is discriminated to switch the operation. The input to the area is processed by the preview processing unit in the I / O CPU, and the input to the other part is processed by the main CPU as usual, so that the user can drag the preview image. When doing so, the problem that the response speed of the preview slows down due to a large amount of data flowing on the bus can be solved. Kill.
